#copy(options = {}) ⇒ Types::CopySnapshotResult

Examples:

Request syntax with placeholder values


snapshot.copy({
  description: "String",
  destination_region: "String",
  encrypted: false,
  kms_key_id: "String",
  presigned_url: "String",
  source_region: "String", # required
  dry_run: false,
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :description (String) —

    A description for the EBS snapshot.

  • :destination_region (String) —

    The destination Region to use in the ‘PresignedUrl` parameter of a snapshot copy operation. This parameter is only valid for specifying the destination Region in a `PresignedUrl` parameter, where it is required.

    The snapshot copy is sent to the regional endpoint that you sent the HTTP request to (for example, ‘ec2.us-east-1.amazonaws.com`). With the AWS CLI, this is specified using the `–region` parameter or the default Region in your AWS configuration file.

  • :encrypted (Boolean) —

    Specifies whether the destination snapshot should be encrypted. You can encrypt a copy of an unencrypted snapshot, but you cannot use it to create an unencrypted copy of an encrypted snapshot. Your default CMK for EBS is used unless you specify a non-default AWS Key Management Service (AWS KMS) CMK using ‘KmsKeyId`. For more information, see [Amazon EBS Encryption] in the *Amazon Elastic Compute Cloud User Guide*.

    [1]: docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html

  • :kms_key_id (String) —

    An identifier for the AWS Key Management Service (AWS KMS) customer master key (CMK) to use when creating the encrypted volume. This parameter is only required if you want to use a non-default CMK; if this parameter is not specified, the default CMK for EBS is used. If a ‘KmsKeyId` is specified, the `Encrypted` flag must also be set.

    The CMK identifier may be provided in any of the following formats:

    • Key ID

    • Key alias

    • ARN using key ID. The ID ARN contains the ‘arn:aws:kms` namespace, followed by the region of the CMK, the AWS account ID of the CMK owner, the `key` namespace, and then the CMK ID. For example, arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef.

    • ARN using key alias. The alias ARN contains the ‘arn:aws:kms` namespace, followed by the region of the CMK, the AWS account ID of the CMK owner, the `alias` namespace, and then the CMK alias. For example, arn:aws:kms:us-east-1:012345678910:alias/ExampleAlias.

    AWS parses ‘KmsKeyId` asynchronously, meaning that the action you call may appear to complete even though you provided an invalid identifier. The action will eventually fail.

  • :presigned_url (String) —

    When you copy an encrypted source snapshot using the Amazon EC2 Query API, you must supply a pre-signed URL. This parameter is optional for unencrypted snapshots. For more information, see [Query Requests].

    The ‘PresignedUrl` should use the snapshot source endpoint, the `CopySnapshot` action, and include the `SourceRegion`, `SourceSnapshotId`, and `DestinationRegion` parameters. The `PresignedUrl` must be signed using AWS Signature Version 4. Because EBS snapshots are stored in Amazon S3, the signing algorithm for this parameter uses the same logic that is described in [Authenticating Requests by Using Query Parameters (AWS Signature Version 4)] in the *Amazon Simple Storage Service API Reference*. An invalid or improperly signed `PresignedUrl` will cause the copy operation to fail asynchronously, and the snapshot will move to an `error` state.

    [1]: docs.aws.amazon.com/AWSEC2/latest/APIReference/Query-Requests.html [2]: docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html

  • :source_region (required, String) —

    The ID of the Region that contains the snapshot to be copied.

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ‘DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.

Returns:

#create_tags(options = {}) ⇒ Tag::Collection

Examples:

Request syntax with placeholder values


tag = snapshot.create_tags({
  dry_run: false,
  tags: [ # required
    {
      key: "String",
      value: "String",
    },
  ],
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ‘DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.

  • :tags (required, Array<Types::Tag>) —

    One or more tags. The ‘value` parameter is required, but if you don’t want the tag to have a value, specify the parameter with no value, and we set the value to an empty string.

#data_encryption_key_id ⇒ String

The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by the DescribeSnapshots API operation.

Returns:

#wait_until(options = {}, &block) ⇒ Resource

Deprecated.

Use [Aws::EC2::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) {|instance| instance.state.name == 'running' }

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —
